Stonehealth

What Stonehealth does

Stonehealth Ltd is a UK-based private company founded by Brian Crowe in the early 1980s and incorporated in 1989, headquartered in Dursley, Gloucestershire. The company designs, manufactures, and distributes specialist cleaning systems used to restore and conserve historic masonry, stonework, and painted surfaces. Stonehealth is the sole manufacturer of two proprietary technologies: the DOFF system, which delivers superheated water at 150°C to remove modern paints, biological matter, grease, oil, and atmospheric soiling; and the TORC system, which uses swirling vortex technology with modulised nozzles introduced in 2000 for precision cleaning that retains surface patina. The company estimates these systems address 90% of unwanted matter types encountered on heritage buildings, replacing legacy invasive approaches such as sand/grit blasting, flooding, and hazardous chemicals.

Stonehealth operates a hybrid go-to-market model combining direct e-commerce sales through the Stonehealth Store (with main units priced at £9,598.80 for DOFF Integra and £11,278.80 for the new DOFFIII), enterprise field sales targeting architects, surveyors, and conservation officers, RIBA-approved CPD seminars, and an extensive certified contractor channel known as the Rosette Scheme spanning the UK, Ireland, the Netherlands, and the United States. Revenue streams include equipment sales, accessories and parts (e.g., DOFF Pole at £547.44, extension hoses, triggers), specialist cleaning products (Paint RID, Cleanfilm III, DOFF De-Scaler), servicing and repairs, training, contractor-led hire from £399 per week, and paid trial reports. The customer base spans heritage organisations, local authorities, restoration contractors, and building owners, with named projects including Westminster Abbey, Oxford and Cambridge Universities, Historic Royal Palaces, the Tower of London, and St. Paul's Cathedral.

The company is founder-led and independently owned, with no external funding, parent company, or public listing documented in the source materials. Stonehealth maintains a multi-channel digital presence across Facebook, Instagram, X, LinkedIn, and YouTube, and runs separate websites for contractors, specifiers, the public store, and the Rosette contractor directory. Sub-brands include DOFF, TORC, and the legacy Jos System. The most recent product release was the DOFFIII in 2024, alongside a biofuel retrofit across the DOFF range, signalling continued investment in the core equipment line.
